HEADLIGHT.

Specification of Letters Patent.

Application filed August 23, 1913. Serial No. 786,280,

Patented Dec. 30, 1913.

To all whom it may concern Be it known that I, JULIUS S. WALSH, acitizen of the United States, residing at St. Louis, Missouri, haveinvented a certain new and useful Improvement in Headlights, of whichthe following is a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to headlights of the type that comprise a casingprovided with a glass front for protecting the light arranged inside ofthe casing.

One object ofmy invention is to provide a headlight of the typementioned in which the glass front is so constructed that it will not beliable to be injured or rendered useless by excessive heat or byvibration.

Another object is to provide a headlight in which the glass front iscomposed of independent sections that are joined or connected togetherin such a manner that one or more of the sections or the parts of abroken section cannot fall out of operative position and thus form ahole or opening in the glass front of the headlight.

Other objects and desirable features of my invention will be hereinafterpointed out.

Figure 1 of the drawings is a perspective view of an automobileheadlight construct-- ed in accordance with my invention; Figs. 2 and 3are front elevational views illustrating other ways of dividing theglass front into sections; Fig. 4: is aneenlarged view of a port-ion ofthe glass front of my improved headlight; and Fig. 5 is a crosssectional view of a portion of the glass front showing the embedded wiremesh that connects the sections of the glass front together.

Referringto the drawings which illustrate the preferred form of myinvention, A designates the casing of a headlight of any particular typeor design, and B designates the glass front which protects the lightthat is arranged inside of the casing A. The glass front B is composedof a plurality of independent sections 1, all of which are joinpd orconnected together in such a manner that one section or the partsof abroken section cannot fall out of place and thus form a hole in theglass front through which air and dirt can enter the casing. It isimmaterial so far as my broad idea is concerned, how theindependentsections 1 of the glass front are united or connected to eachother as my broad idea consists in a headlight of any type or designequipped with a glass front composed of a plurality of independentsections separated from each other by cracks orspaces and connectedtogether in such a manner that there is no possibility of one section orthe parts of a 1 broken section dropping out of place. I prefer,however, to connect the sections 1 to each other by means of a piece ofwoven wire fabric 2 that is embedded'in said sections during theoperation of forming the glass, as shown in Fig. 5. The joints, cracksor spaces-3 between the sections 1 permit said sections to expand andcontract, thus eliminating the possibility of the glass front becomingcracked or broken by excessive, heat, and said joints or spaces 3 alsoelimivnate the possibility of the glass front becoming cracked or brokenby excessive vi-' bratio-n. The wire mesh or woven wire fabric 2 that isembedded in the sections 1 "reinforces and strengthens the glass andembedded in the glass.

The particular shape and size of the sect-ionsl .is immaterial so far asmy invention is concerned. In the form illustrated in Fig. 1 the glassfront B is provided with substantially square sections 1; in the formillustrated in Fig. 2 the glass front B is provided with substantiallyoblong-shaped sections 1; and in the form illustrated in Fig. 3 theglass front is composed of a substantially ring-shaped outer section andfour substantially triangular-shaped sections arranged inside of same.

In a headlight of the construction abovedescribed there is littleliability of the glass front being rendered useless or becoming brokenin such a way that air and dust can strike the light arranged inside ofthe casing of the headlight owing to the fact that the glass front iscomposed of independent secby the expansion and contraction of the 80 ofthe same together for preventing said seclight or to any particularmanner of connecting the independent sections of the glass fronttogether.

It is to be noted that wire glass may be divided in the manner shown bysimply cutting the same with an ordinary glass cutter and extending thecrack formed by the cutter by'tapping gently on the glass. In thismanner the mm is not broken.

Having thus described my invention, what -I claim as new and desire tosecure by Letters Patent is:

1. A headlight provided with a glass front 4 composed of independentsections that are joined or connected together by means embedded in saidsections.

- 2. A headlight provided with a glass front composed of lndependentsections or pieces of glass, and means embedded in said sections andjoining the meeting edge portions tions from separating or the parts ofa broken section from falling out of position. .3. A headlight providedwith a glass front said sections and operating to hold said sections inoperative position with relation to each other without mterfering withthe relative movement of said sections caused by vibration and bycontraction and expansion of the glass.

.4. A headlight front consisting of a pinrality of independent glasssections having a continuous Wire mesh fabric embedded therein andconnecting said sections.

5. A headlight provided with a glass front consisting of a plurality ofindependent sections arranged in vertical and transverse rows and havinga continuous Wire mesh fabric embedded therein andconnecting saidsections. a

6. A headlight provided with a glass front that is made up of aplurality of independent sections or pieces 'of glass, and a flexiblemetallic means embedded in said sections to connect the meeting edgeportions of said sections directly together so as to prevent one sectionor the parts of a broken section from falling out of operative position.

In testimony whereof I hereunto aifix my signature in the presence oftwo witnesses, this 12th day of August 1913.
